What structure holds the two sister chromatids together as they prepare for cell division.
otez555 [7]

Two sister chromatids are held together by the centromere

<h3>The Chromosome</h3>

The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.

Each of the sister chromatids carries an allele of the same gene.

The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.

More on the chromosome can be found here: brainly.com/question/296477

Lesechka [4]

The dominant RR (red) and recessive rr (white). The color pink seems to be an intermediary between the dominant and recessive parent. Thus a heterozygote (Rr) that contains both a dominant and recessive gene will have a pink color.
